When do you send a change in Elevation and to the nearest what?

• A. If the difference is greater than or equal to 35 meters, to the nearest 5 meters
• B. If the difference is greater than or equal to 15 meters, to the nearest 10 meters
• C. If the difference is greater than or equal to 50 meters, to the nearest 20 meters
• D. Only when requested by the observer

Answer: (A)

Change in elevation is the vertical correction you send to the gun line when the vertical difference between where the target is and your current fire solution is large enough to warrant an adjustment. You send this correction when that elevation difference is 35 meters or more, and you round the correction to the nearest 5 meters. The 35-meter threshold keeps communications efficient by avoiding small, frequent corrections, while the 5-meter rounding provides a practical, standardized increment that matches how elevation changes are applied with ballistic data.
